A versatile template-assisted strategy for the preparation of monodispersed rattle-type hybrid nanospheres, encapsulating a movable Au nanocore in the hollow cavity of a hairy eletroactive polymer shell ([email protected]@PTEMA-g-P3HT hybrid nanorattles; PTEMA: poly(2-(thiophen-3-yl)ethyl methacrylate; P3HT: poly(3-hexylthiophene), is reported. The [email protected] core-shell nanoparticles, prepared by the modified St?ber sol-gel process on Au nanoparticle seeds, were used as templates for the synthesis of [email protected]@PTEMA core-double shell nanospheres. Subsequent oxidative graft polymerization of 3-hexylthiophene from the exterior surface of the [email protected]@PTEMA core-double shell nanospheres allowed the tailoring of surface functionality with electroactive P3HT brushes ([email protected]@PTEMA-g-P3HT nanospheres). The [email protected]@ PTEMA-g-P3HT hybrid nanorattles were obtained after etching of the silica interlayer by HF. The as-prepared nanorattles were dispersed into an electrically insulating polystyrene matrix and for the first time used to fabricate nonvolatile memory devices. As a result, unique electrical behaviors including insulator behavior, write-once-read-many-times and rewritable memory effects, and conductor behavior as well, were observed in the [email protected]@PTEMA-g-P3HT+PS/ITO (ITO: indium-tin oxide) sandwich thin-film devices.
Luxin Wang studied Materials Chemistry at the East China University of Science and Technology (ECUST) and received his BS degree from ECUST in 2012. He then joined Prof. Dr. Yu Chen?s group as a PhD student. So far he has published several articles in the international peer-review journals. His present work is mainly focused on the design and synthesis of electro active functional materials for polymer memory devices.
